I remember that one. but that's not quite in the same boat as the
automatically running attached shell script or vbs file = stupid stupid
bug in MIME parsing = whoops! bad code, but not quite stupid
And that "UNIX virus" mail claimed "It contains (sic) of a so-called shell
script which, when executed [...]" rather than mentioning overflowing
buffers or exploiting a bug...
I agree that theoretically you could set up a UNIX mail virus, but without
a really really badly designed security model overall (viz Outlook and
Windows) it's not going to get very far if it has to rely on various
buffer overflows and bugs in a myriad of different mailreader versions to
get itself run.

yep, there was a buffer overflow if I recall correctly, found in nmh a
coupla months ago :( Of course a fix was released in a few days and all
the vendors have binaries for it on their websites.
